v0.8: self-hosted fonts replace the Google Fonts CDN link

index.html now loads /api/fonts/fonts.css, synthesized at request time
by goods-editor's mountEditorApi from the host's fonts/ directory
(populated via fetch-fonts in goods-editor-module — the host-local
fetch script shrinks to a pointer). Shipped synchronously in <head>
on purpose: the module's runtime injector races first paint and the
editor's text measurement gives wrong answers against fallback
metrics until real fonts load.

+      Fonts are served by the goods-editor module from the host's fonts/
+      directory (populated by `npm run fetch-fonts` in goods-editor-module).
+      mountEditorApi synthesizes the @font-face rules at request time
+      based on whatever .ttf/.otf/.woff2/.woff files are present, so
+      adding a font is a "drop file + restart" workflow with no code
+      change here. See goods-editor-module/src/server/fontRegistry.js
+      for the generator.
+
+      We deliberately ship this synchronously in <head> rather than
+      letting the module inject a <link> at mount time: the module's
+      runtime injector races first paint, and the editor's font-
+      dependent text measurement (`measureTextWidth`) gives wrong
+      answers against fallback metrics until the fonts load. The
+      host pays a tiny extra TTFB to make first paint correct.
+      <ApparelDesigner loadFonts={false}> in App.jsx / CustomizeRoute
+      tells the module not to also inject its own runtime tag.
